The following describes an optical transport network service access method according to an embodiment of the present invention with reference to fig. 1.
Fig. 1 is a flowchart of an embodiment of an optical transport network service access method according to the present invention. As shown in fig. 1, the method of this embodiment includes:
step S102, the comprehensive network manager responds to the service opening request and inquires the end node access equipment related to the service to be opened, wherein the end node access equipment comprises source end access equipment and sink end access equipment.
The integrated network management can determine the end node access device related to the service to be opened according to the service source and destination node information in the work order for opening the service to be opened.
Step S104, the integrated network manager determines the device network manager to which the end node access device belongs according to the attribute information of the end node access device.
Attribute information for the end node access device includes information such as vendor, type, etc., but is not limited to the examples given.
Step S106, the comprehensive network management instructs the device network management of the end node access device to obtain and return the access resource information of the end node access device.
The access resource information includes at least one item of port mapping mode and available cross resource, and the access resource information also includes the use state of the end node access equipment port and the service type supported by the port.
The integrated network manager may instruct, for example, a device network manager to which the end node access device belongs to obtain and return access resource information of the end node access device by calling a related interface, where an exemplary implementation method is as follows:
the comprehensive network management calls a device port information query interface to indicate the device network management which the end node access device belongs to obtain and return the port mapping mode of the end node access device, the use state of the device port and the service type supported by the port. The parameters involved in the interface may include, for example: ClientServiceTypeList (type of traffic supported by the port), ClientServiceMappingMode (mapping mode supported by the port), but are not limited to the examples given.
The comprehensive network manager calls the equipment cross resource query interface to indicate the equipment network manager to which the end node access equipment belongs to acquire and return the available cross resources of the end node access equipment. The parameters involved in the interface may include, for example: currentCCCapacity (available cross capacity of the device), but is not limited to the illustrated example.
Step S108, the integrated network management judges whether the access resource information of the end node access equipment meets the requirement of the service to be opened, thereby determining whether the service to be opened can be accessed.
One implementation method of step S108 is as follows: the comprehensive network management judges whether the end node access equipment has a port supporting the service type of the service to be opened, judges whether the port of the end node access equipment supporting the service type of the service to be opened is idle, further judges whether available cross resources of the end node access equipment meet the service rate required by the service to be opened if the port of the end node access equipment supporting the service type of the service to be opened is idle, further judges whether port mapping modes of the source end access equipment and the sink end access equipment are consistent, if the judgment result shows that the available cross resources of the end node access equipment meet the service rate required by the service to be opened and the port mapping modes of the source end access equipment and the sink end access equipment are consistent, the service to be opened can be accessed, and otherwise, the service to be opened is not allowed.
Alternatively, one implementation method of step S108 is: the comprehensive network management further judges whether the available cross resources of the end node access equipment meet the service rate required by the service to be opened from the idle port supporting the service type of the service to be opened, if the judgment result is that the available cross resources of the end node access equipment meet the service rate required by the service to be opened, the service to be opened can be accessed, otherwise, the service to be opened is not allowed to be accessed.
Alternatively, one implementation method of step S108 is: the integrated network management further judges whether the port mapping modes of the source access equipment and the sink access equipment are consistent from the idle ports supporting the service types of the services to be opened, if the judgment result is that the port mapping modes of the source access equipment and the sink access equipment are consistent, the services to be opened can be accessed, otherwise, the services to be opened are not allowed to be accessed.
By analyzing the relevance of the service requirement and the access resource of the end node access equipment and combining the characteristics of the optical transmission network, the service access capacity is comprehensively analyzed according to the port mapping mode, available cross resources and other information, the analysis blind zone existing in the existing service access analysis method is eliminated, the mismatching between the operator transmission network resource and the user service is avoided, the accuracy of service access capacity judgment is improved, the service opening efficiency is improved, and the user experience is improved.
The following describes a processing method after the integrated network management determines whether the service can be accessed with reference to fig. 2.
As shown in fig. 2, the method for accessing services to an optical transport network further includes, after step S108:
step S210, if the integrated network manager determines that the service to be provisioned may not be accessed, for example, the port mapping modes of the source access device and the sink access device are not consistent, the integrated network manager adjusts the port mapping modes of the source access device and the sink access device to be consistent according to the service type of the service to be provisioned, and then the service to be provisioned may be accessed.
The port mapping mode mainly includes, for example: AMP (Asynchronous Mapping Procedure), BMP (Bit-synchronous Mapping Procedure), GMP (generalized Mapping Procedure), GFP-T (Transparent mode Generic Framing Procedure), but not limited to these examples. Under the condition that the port mapping modes of the source end access device and the sink end access device are not consistent, the comprehensive network management determines the mapping mode according to the service type of the service to be opened, and then adjusts the mapping modes of the ports of the source end access device and the sink end access device to be consistent, for example, the service is a GE service, the mapping mode should select GFP-T, if the mapping mode of the port of a certain end device is in other mode, the comprehensive network management adjusts the mapping mode to be GFP-T, but not limited to the examples.
Step S212, if the comprehensive network manager determines that the service to be opened can be accessed, the access resource of the end node access equipment is marked as pre-occupied.
The method can realize automatic matching and setting of the access modes of the source terminal access equipment and the sink terminal access equipment, and improve the analysis and management capability of the access resources of the optical transport network service. Meanwhile, the access resource of the end node access equipment meeting the service opening requirement is marked as pre-occupied, and the access resource of the end node access equipment is not judged when other service opening requests come, so that the accuracy and the efficiency of judging the service access capacity are improved.
A preferred embodiment of step S108 is described below in conjunction with fig. 3.
